Hidden Costs Many Installers Won’t Tell You
In Nigeria, many clients underestimate these:

Ignoring these leads to system failure or extra costs later.
Why Cheap Solar Installations Fail
Low-cost systems often fail due to:

No proper load calculation
Inexperienced technicians
A properly designed system should start with a load audit, not guesswork.
